       9. A method of delivering microporation medical treatments to improve biomechanics comprising:
 generating, by a laser, a treatment beam on a treatment-axis not aligned with a patient's visual-axis in a subsurface ablative medical treatment to create an array of micropores that improves biomechanics; 
 controlling, by a controller in electrical communication with the laser, dosimetry of the treatment beam in application to a target tissue; 
 focusing, by a lens, the treatment beam onto the target tissue; 
 monitoring, by an automated off-axis subsurface anatomy tracking, measuring, and avoidance system, an eye position for application of the treatment beam; and 
 wherein the array pattern of micropores is at least one of a radial pattern, a spiral pattern, a phyllotactic pattern, or an asymmetric pattern, and wherein the array pattern of micropores has a controlled asymmetry which is an at least partial rotational asymmetry about the center of the array pattern and extends to at least 51 percent of the micropores of the array pattern.
